    Hello, I have a supervisor password locked bios that I tried patching it following steps at this thread, but after I write the patched rom to the chip and boot, the bios beeps 4 + 4 times and I get no display, rewriting the original rom back makes it POST but I'm immediately asked for password.

    Any idea what's the issue or if y'all can try to patch the attached rom it would be greatly appreciated.

    Today, I tried the unlocked bios provided in this thread, after removing CMOS battery i get black screen and it powers back off and doesn't auto-restart. Original dump still gets to password prompt for sanity check.

          Elitedesk 800 G6 SFF Bios Password Lock XM25QH128A (3.3v) - Am I doing this right?
          by BrentH561
          Hello everyone, I am looking for help to make sure I am on the right track to remove lost BIOS Admin password on an HP EliteDesk G6 800 SFF. I recently purchased this on ebay and the seller is willing to accept a return but I have already installed my new HDs, NVME, and setup proxmox so I would like to keep it.

          Here is the hardware identification specs:
          HP EliteDesk 800 G6 SFF
          Intel(R) Core(TM) i5-10500 CPU @ 3.10GHZ 16384 MB RAM
          Serial No: MXL1223499
          Product No: 26S74UT#ABA

          BIOS/IC chip seems to be the 4 pin XMC XM25QH128A (3.3v). However most

          ASUS TP500LA BIOS request/repair/merge?
          by jbonavita
          Hi, my laptop wont boot at all
          With original bios no POST, only LED lights
          With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
          Some issues
          A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
          B- If updated from 500LN version 203 to 300, the battery stops being recognized

          Things I tried

          1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

          Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
          by Wahaz
          Hello,

          I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
          So I thought it was a Bios problem.
          I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
